Proxy Protocol to Fake IP example service, yes/no? alt?

[elico]

I have a scenario which I need to pass the original IP address to a legacy service that doesn't support PROXY protocol at all.
Another issue with the infrastructure(cloud vendor) is that the LB service will not fake the originating source IP and enforces strict IP+mac pairs.
So for temporary solution I am trying to compose a proxy service that will receive PROXY protocol and will open a new local connection on the 'lo' interface with the fake source IP.
It's on Linux so I will try to use TPROXY.
I will be happy for suggestions.

• The same issue exists ontop of AWS/OpenStack/Others and can be tested there. I am almost sure that F5 integration inside OpenStack some how have a resolution for this issue.
